3,039,797 KEQDLENG ABRASHVE QOATING, METHOD, AND CiIPATED OBEEGT Hans L. Levi, 300 Broadway, Dobhs Ferry, NX. Fiied May 5, rate, Ser. No. 27pm ll Claim. (\Cl. 149-30) This invention relates to coated kindling abrasives and more particularly to a composition of matter suitable for application upon any suitable surface to create a striking or kindling surface for matches and the like, and to the method for applying the same, as well as the coated matchbook.

Existing methods for applying a striking surface on match booklets or boxes have certain disadvantages. Usually the striking surface is brushed or sprayed on. In some cases an adhesive is applied first and, while wet, covered with pulverized striking material. Since the wet striking surface must be dried under heat, prior to subsequent operations, this operation is slow when contrasted to the fully automatic printing, cutting and forming of the match containers.

Also, since the adhesive base of the prior art methods is water soluble, the conventional striking surface is most sensitive to moisture and becomes useless if exposed to water, or even damp air. As everyone has experienced, a striking surface so exposed deteriorates and crumbles when struck by a match head.

Further, the prior art surfaces are not perfectly neat, and are drab and usually are of simple rectangular shape.

The present invention overcomes the above disadvantages in that it permits application of a striking surface as rapidly as the printing of decorative matter on the match container without delay for drying under heat. Further, it permits a striking surface to be applied in irregular shapes so as to become a part of the general design. Color pigments may be added, producing a decorative and attractive while neat and cleancut striking surface. In addition, it provides a striking surface insensitive to moisture which will work under all climatic conditions.

These and other objects will become apparent in the following description and in the drawings, in which:

FIG. 1 is a perspective view of a booklet of matches;

FIG. 2 is a diagrammatic representation of apparatus illustrating the method of the present invention; and

FIG. 3 is a cutaway perspective view of a treated surface.

Referring now to the drawings, FIG. 2 shows two roughening or embossing roll-s and 11, printing rolls 12 and 13, transfer roll 14 and pick up roll 15, which is immersed in reservoir 16 as shown.

The apparatus in FIG. 2 may be either a selfcontained independent piece of equipment or an attachment made part of the printing press at the point where the cardboard strip leaves the press but before it is cut or formed.

The apparatus is simple in structure and operates as follows. Cardboard strip 17 enters between embossing rolls 1G and 11, where the surface upon which the mixture is to be applied is roughened or embossed in preparation to provide roughened portion 18. (See also FIG. 3.) So roughened, the cardboard strip proceeds to printing rol-ls 12 and 13 where an abrasive coating 19 of the mixture is rolled or printed onto the strip by roller 13. The latter is fed by roll 14 which transfers the mixture supplied by pick up roll from the reservoir 16. The mixture in the reservoir may be agitated to maintain proper homogeneity by, for example, a paddle wheel stirrer (not shown) driven from the pick up roll by compressed air or any other conventional means.

I have found the following proportions in the coating composition to be exemplary and highly satisfactory in procuring the desired efiects.

Percent Ingredients: by weight 4 lbs. cut shellac 25 Denatured alcohol 25 Phosphorous, red, amorphous 30 Manganese metal, powdered 10 Antimony metal, powdered 8 Glass powder, 200 mesh 2 Retarder, if required, may be added, as may color pigment, if so desired. The mixture does not require exactly the proportions disclosed, but a tolerance of plus or minus ten percent of any of the individual ingredients will still result in a suitable mixture.

It is to be understood that certain variations in the proportions and ingredients disclosed may be made by those skilled in the art without departing from the scope and spirit of the invention.

What is claimed is:

A kindling abrasive coating composition which can be printed on the striking surface of match booklets and the like and which is quick-drying at ambient temperature without the necessity of applying heat, comprising a mixture by weight of about 30% amorphous red phosphorus, about 10% powdered manganese, about 8% powdered antimony, about 2% ground glass 200 mesh, about 25% cut shellac and about 25% denatured alcohol.
